About this study
Official title: A Multicenter, Double-Blind, Randomized, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Y-3 in Chinese Subjects With Acute Ischemic Stroke
This trial aims to evaluate the effectiveness and safety of Y-3 for injection in the treatment of patients with acute ischemic stroke within 48 hours of onset
Read the detailed description
A multi-center, randomized, double-blind, parallel, placebo-controlled trial design was adopted, and subjects were randomly assigned to Y-3 for injection group and placebo group in a 1:1 ratio. randomization stratification factors include: onset time (≤12 hours, >12 hours) and research site.
Treatment was continued for 10 days (10 times), and follow-up was conducted until the 90th day from the first dose.
The trial is divided into three phases: screening/baseline phase, treatment phase, and follow-up phase.
Screening/baseline period: After the subjects sign the informed consent form, they enter the screening/baseline period for screening examination.
Treatment period: Qualified subjects are randomly divided into groups in a 1:1 ratio and receive continuous treatment for 10 days (10 times) with Y-3 for injection and placebo respectively. During the treatment period, relevant examinations and evaluations required by the protocol will be carried out; PK blood samples from subjects were collected for population pharmacokinetic analysis.
Follow-up period: Subjects who have completed treatment will enter the follow-up period until the 90th day of treatment.

What participants receive

Y-3 for injectionDrug
Qualified subjects were randomly divided into groups in a 1:1 ratio and received continuous treatment with Y-3 injection (40 mg/dose, qd) or placebo control drug. The treatment was performed 10 times for 10 days.
Placebo control groupDrug
Qualified subjects were randomly divided into groups in a 1:1 ratio and received continuous treatment with Y-3 injection (40 mg/dose, qd) or placebo control drug. The treatment was performed 10 times for 10 days.
| Study group | Role | What they receive |
|---|---|---|
| Y-3 for injection test group | Experimental | The special solvent Y-3 for injection was extracted with a sterile syringe and injected into a Y-3 lyophilized powder vial for injection.

What is being measured
The primary outcome is the main question the study is designed to answer.
The proportion of subjects with Modified Rankin Scale(mRS) score ≤ 1 on the 90th day of treatment
Measure the scores of subjects using the Modified Rankin Scale(mRS) scale.Measure on the 90th day of treatment to evaluate the effectiveness of the medication.The Modified Rankin Scale(mRS) score of this study ranged from 0 to 5. The higher the score, the worse the recovery, and the lower the score, the better the recovery.
Measured: On the 90th day of treatment
Secondary outcomes (4)
Good functional prognosis on the 90th day of treatment
Modified Rankin Scale(mRS) score corrected based on baseline National Institute of Health stroke scale(NIHSS) score. The baseline National Institute of Health stroke scale(NIHSS) score of 4-7 is 0 on the 90 day Modified Rankin Scale(mRS) score; The baseline National Institute of Health stroke scale(NIHSS) score of 8-14 is 0-1 on a 90 day Modified Rankin Scale(mRS) score; The baseline National Institute of Health stroke scale(NIHSS) score is 15-25, with a 90 day Modified Rankin Scale(mRS) score of 0-2. Measure on the 90th day of treatment to evaluate the effectiveness of the medication.
Measured: On the 90th day of treatment
Modified Rankin Scale(mRS) displacement analysis on the 90th day of treatment;
Measure the scores of subjects using the Modified Rankin Scale(mRS). Measure on the 90th day of treatment to evaluate the effectiveness of the medication.The Modified Rankin Scale(mRS) score of this study ranged from 0 to 5. The higher the score, the worse the recovery, and the lower the score, the better the recovery.
Measured: On the 90th day of treatment
The proportion of National Institute of Health stroke scale(NIHSS) scores reduced by ≥ 4 compared to baseline on the 10th and 30th day of treatment;
Measure the scores of subjects using the National Institute of Health stroke scale(NIHSS). Measure on the 10th and 30th day of treatment to evaluate the effectiveness of the medication.National Institute of Health stroke scale(NIHSS) A larger difference from baseline means a better patient recovery, and a smaller difference means a worse patient recovery.
Measured: On the 10th and 30th day of treatment
The proportion of individuals with Barthel Index score ≥ 95 on the 90th day of treatment on the Activities of Daily Living Scale.
Measure the scores of subjects using the Barthel Index scale. Measure on the 90th day of treatment to evaluate the effectiveness of the medication.The total score of the Barthel Index is 100.The higher the Barthel Index scale score, the better the recovery, and the lower the score, the worse the recovery.
Measured: On the 90th day of treatment

This trial aims to evaluate the effectiveness and safety of Y-3 for injection in the treatment of patients with acute ischemic stroke within 48 hours of onset
Detailed description
A multi-center, randomized, double-blind, parallel, placebo-controlled trial design was adopted, and subjects were randomly assigned to Y-3 for injection group and placebo group in a 1:1 ratio. randomization stratification factors include: onset time (≤12 hours, >12 hours) and research site.
Treatment was continued for 10 days (10 times), and follow-up was conducted until the 90th day from the first dose.
The trial is divided into three phases: screening/baseline phase, treatment phase, and follow-up phase.
Screening/baseline period: After the subjects sign the informed consent form, they enter the screening/baseline period for screening examination.
Treatment period: Qualified subjects are randomly divided into groups in a 1:1 ratio and receive continuous treatment for 10 days (10 times) with Y-3 for injection and placebo respectively. During the treatment period, relevant examinations and evaluations required by the protocol will be carried out; PK blood samples from subjects were collected for population pharmacokinetic analysis.
Follow-up period: Subjects who have completed treatment will enter the follow-up period until the 90th day of treatment.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Y-3 for injection in people with Acute Ischemic Stroke, run by Beijing Tiantan Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The proportion of subjects with Modified Rankin Scale(mRS) score ≤ 1 on the 90th day of treatment (time frame: On the 90th day of treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06517173, which also lists 25 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2026.
